Reserve Resources And Save On Costs
In the case of certain services like Amazon EC2 and Amazon RDS, you will have the option to invest in reserved resources earmarked for your use. With these ‘Reserved Instances’, you access the opportunity to save quite a bit by tailoring resource usage to meet real time demand of your clients. Reserved Instances offered by Amazon Web Services come under three payment choices – All up-front Reserved Instances (AURI), partial up-front Reserved Instances (PURI) or no upfront Reserved Instances (NURI).
Common across all three choices is the direct correlation between your investment and long term cost savings. Simply put, the larger your direct payment, the bigger the discount. To maximize your savings, youmay opt for paying all resource reservation costs up-front and accordingly receive the largest discount.
